Hello,
Thank you very much for your source, it's really too nice.
There is a little mistake when select item in the combox, this is due to a forgoten "," in the initialisation of Query[NUM_OF_QUERIES][50] in SysInfoDefs.h after
"Hard Disk Features (S.M.A.R.T.)"
Best regards
Aramii.

Hi Razi,
Your source for retrieving system informations is very good and very clear!
It helped me a lot with a small project (getting status and notifications of a server, when something is not working properly). The other acrticles of yours are also very good, especially the one about GPS. I just want to say thank you for your good help. 
**We are an example of helping each other**

Mr. A.Razi,
I hope you can answer on this question, if you're able to make some time free in your valueble free spare time. How can I distinguish between a USB memory stick and a Harddisk drive? Because when I connect a usb stick into the pc, I get the USB memory size and etc...
Suddenly in my mind comes up to check the filesystem type ( HDD = NTFS, USB = FAT32 ), something like that. What do you think about that?

I have some questions about HD Physical information. Can you help me in this regard.
Questions:
1)Where the Physical information( say Cylinder, Head, Sector)reside?
2) How can I get these information?

Hi, great program.
Any code or thoughts on how to detect S.M.A.R.T. info for SCSI drives?
Thanks,

I tried to retrive the CPU serial number of the AMD 64 but it doesn't work . What must I do to get the 64 bit procesor serial number.
Thanks

If I remembered correctly, the code only works with Intel CPUs. Try google or AMD site to find some code for retrieving CPU serial number.
Best regards,
A. Riazi

Hi Abbas
I compiled and executed your sample, I recieved a error in the edit box when I chose Partitions from the combo. So I took a look a your source code.
Heres what I discovered:
In QueryPartitions funtion, the call to DeviceIoControl will sometimes fail with the error code ERROR_INSUFFICIENT_BUFFER. This is because the struct DRIVE_LAYOUT_INFORMATION_EX that needs to be passed to DeviceIoControl is variable length, the size of the data returned depends on the number of drives, and partitions.
In addition, some driver implementations will return a partial buffer, they will simply write whatever data they can fit into the buffer. DeviceIoControl will fail with error code ERROR_MORE_DATA in this case.
These conditions can be handled by doing the following:
First change variable dli declaration to:
DRIVE_LAYOUT_INFORMATION_EX* dli = NULL;
Here is the code to insert:
DWORD dwbytes=0;
DWORD dwlastErr = 0;
int i=0;
do
{
if(NULL != dli)
{
delete[] (char*)dli;
dli = NULL;
}
DWORD datasize = sizeof(DRIVE_LAYOUT_INFORMATION_EX) + i * sizeof(PARTITION_INFORMATION_EX);
dli = (DRIVE_LAYOUT_INFORMATION_EX*)new char[datasize];
if(dli)
{
bResult=DeviceIoControl(hDevice,IOCTL_DISK_GET_DRIVE_LAYOUT_EX,NULL,0,dli, datasize,&dwbytes,(LPOVERLAPPED) NULL);
dwlastErr = GetLastError();
i++;
}
}
while((dwbytes == 0 && dwlastErr == ERROR_INSUFFICIENT_BUFFER) || dwlastErr == ERROR_MORE_DATA);
The code needs to be modified here:
while (hDevice!=INVALID_HANDLE_VALUE)
{
***DELETE OLD CODE HERE***
***INSERT NEW CODE HERE***
if (bResult)
{
Then at the bottom of the QueryPartitions function add:
if(NULL != dli)
{
delete[] (char*)dli;
dli = NULL;
}
I believe something similar is required for each function where you are calling DeviceIoControl. Additional error handling is required.
Thanks for your articles, I look forward to your future contributions!

Hi,
You have two options for getting system informations:
1- WMI
2- Win32 API (like the one that I did).
I suggest you to read Win32 API documentations.
Best regards,
A. Riazi

Can you please include a function to retrieve hard Drive serial number (atleast first drive). It would be very helpful.
Thanks

At line 286 in SysInfoDefs.cpp you wrote:
ceil(memoryStatus.dwTotalPhys/1024/1024)
It should be:
ceil(memoryStatus.dwTotalPhys/1024.0/1024.0)
if you want the ceil function to have an effect.
The best would be:
ceil(memoryStatus.dwTotalPhys/1048576.0)
One division less
